Human Heart Beat in Harmony with the Earth's Heartbeat

Last week, a friend was telling me about a radio show they heard where Gregg Braden talked about the earth's pulse. Apparently the frequency has matched that of the human heartbeat since the 70's (?) when scientists began measuring it. Since 1980, it has begun to speed up, and on 9/11 there was actually a giant spike in the earth's pulse. I find this all very interesting when thinking about how everything is so interrelated. I haven't been able to find the radio show or much other info backing this story so far, but I did find a quote from Gregg Braden's book:

"Each cell of your body is constantly shifting patterns of energy to achieve harmonic resonance to the reference signals of our planet.... This module, our mind-spirit-body complex, when placed within the fields of another module (planetary or human) will have a tendency to move into resonance with the higher vibration. In the human energy system, however, the process takes on an additional component: the willingness of the conscious mind governing the body to adapt to the new range of vibration. The primary tool of adaptation is life itself, complete with the bundle of emotion , attitudes, perceptions, fears, and beliefs that provide the framework for the challenges of life. One key factor in this process is the willingness of the individual to achieve balance within the energetic system using the tools of Choice and Free Will. These are the basic tools used to release old patterns of belief, lifestyle, or relationships and adapt to new, more balanced patterns.... The ancients taught meditative techniques to bypass the logical mind in an effort to consciously feel these vibrations as well as sense the pulses of light....
Earth's fundamental vibration has accelerated gradually, with the greatest increase beginning in 1987.... The net result of this increase is that each cell of our bodies seeks to match the rhythmic "heartbeat" or reference frequency, to that of Earth. Moving into the resonant pattern of a higher tone, each life form, including human, is attempting to map out a new rhythm, or "signature frequency." This frequency is indicative of the composite vibration of Earth at a given point in time. It would be possible to entrain the cellular heartbeat of the physical body immediately, if it were not for variables that provide resistance to the entrainment, such as belief systems. To the degree that an individual clings onto structures and beliefs that no longer fit into the new paradigm, to that degree will the individual encounter resistance to the entrainment of cellular frequency with planetary frequency.
What is the target value of Earth's shifting frequency of resonance? Where will the base resonant frequency of Earth be at the close of the cycle? [Braden speaks of a 200,000 years cycle.]
Historically Earth has pulsed at approximately 8 cycles per second, 7.8 until recently. This value has been so stable that global military communications have developed relying upon this "constant." As of this writing (3rd copyright 1997), the oscillations are increasing, having moved into the range of 8.6 cycles per second. The target frequency of Earth resonance is the next member in the sequence of values that govern this parameter: 13 cycles per second. It is 13 cycles per second that may become our new base resonant frequency with all harmonics based upon integer multiples of this fundamental vibration. This is the frequency that may trigger resonance with the new grid-matrix complex, signaling the close of the present cycle of evolution and the beginning of the "New Age." If ancient timetables are correct, it will happen within our lifetime."
